protected Caret createCaret()
protected Highlighter createHighlighter()
protected String getKeymapName()
protected Keymap createKeymap()
The set of bindings used to create the keymap is fetched
from the UIManager using a key formed by combining the
getPropertyPrefix()
method
and the string .keyBindings
. The type is expected
to be JTextComponent.KeyBinding[]
.

NOTE:The View hierarchy can be traversed from the root view, and other things can be done as well. Things done in this way cannot be protected like simple method calls through the TextUI. Therefore, proper operation in the presence of concurrency must be arranged by any logic that calls this method!
